In the accompanying diagram of a parallelogram ABCD ,DC= 5x-18, BC=3x-6, AB=2x+12 find measure BC. Please help

BC = 39

Step-by-step explanation:

Given:

DC = 5x - 18,

BC = 3x - 6,

AB = 2x + 12

Opposite sides of a parallelogram are equal.

Therefore:

AB = DC

2x + 12 = 5x - 18

Collect like terms

12 + 18 = 5x - 3x

30 = 2x

Divide both sides by 2

15 = x

x = 15

BC = 3x - 6

Plug in the value of x

BC = 3(15) - 6 = 45 - 6

BC = 39

step-by-2step explanation:

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
